f/ if I fave/jar mm mm ise nnme ravioli i To all whom, itmay cancer 1i Be it known that T, WILLIAM LINTERN, a c1t1zen of the United States, residing at Cleveland, in the county offCuyahoga and State of Ohio, have invented a certain new and useful Improvement in Sanding De-f vices, ofwhichthe following is a full, clear, and exact description, reference beingxliad to the accompanying drawings.

The object of this invention is to provide a simple, eflicient and readily operable sanding device designed to release sand so that it may pass onto a trackway to enable a device rolllng thereon to obtain propertra'c tion. My sander is designed to be electrically operated and to release sand at'the. bottom of a receptacle, allowing the desired quantity of it to descend by gravity. The

sander has various adaptations. I have found it particularly useful for embodiment on traveling cranes for sanding the track on which'either the bridge member or trolley runs. This sanding device results in immediate application of sand to the'track;

insuring a good traction. notwithstandinggrease, snow or iceon the track, and thus increases the eiiiciency and safety of the crane operation.

My sander isshown in the drawings hereof embodied both on the bridge member and trolley ofja traveling crane, and is hereinafter more fully described, and itsesse'nti al characteristics are summarized'in the claims.- In'the, drawings, Figure lais 'a side;'eleva-. tion partly broken away of a traveling crane, wherein 'four of my sandingjdevices,

are provided for sanding thetwo' rails on which the bridge member'travel's and the two rails on the bridge memberonwhich the trolley travels; Fig. 2 is a fragmentary end elevation of Fig.1, showing the "outside of the sandmg devlce at right angles.

Fig. iris cross-section on the line of Fig. 3; I" I: Referring more particularly to Figs. :3

and4, the sand container of my device consists of an upright tank 10, preferably rec'-. tangular in cross section, having near its bottom inclined partitions 11 to make a hopper.- The "tank'preferably has its I own supportingb'ottom 12 independent of the hopper walls. Secured to this bottom at the base of the hopper is a plate 13, having a central orifice, being preferably round,

and theplate being curled down at the edge of the orifice, as shown atl l-in Fig; 3. This plate is preferably secured to the base112 of the receptacle by rivets 15. The outer edgeof the plate; 13 forms the hopper plates 11;

member having at its upper. edgef 'a'n, out

ward flange 21 by which it is securedfto thebottom of the receptacle and below this contracting conically and having at its lower end aninternally threaded 1 portion] 23 into which the discharge pipe 24f screws.

I have shown the same rivets 15 securing the discharge member'and the plate 13' to the bottom "12.

Within the'sand receptacle is closed housing 30 preferably. made of. sheet metal plate 13'and the bottom of the housing and screw.threadedbolts 32 occupying thesetubes and screwing into the plate andbottom of the housing. Within" thehousing 30 is a solenoideO standing vertically and I supported by the base of the housing; Vith in the; upper portion of thisfsolenoid is an iron core Q1 which extends above the solenoid and terminates in a head 42'. A'comand supported ashortdistance' above the base ofthe receptacle by suitable 'legs. The

legs shown-consist of tubes 31' between the* pression spring 4.3.. surrounds the core be tween'the head and the top of the solenoid andtends. to raise the cores, At its lower end the core is connected wlth a non-inagi netic extension bar-45 or brass'orotheris'uitable material, which passes downwardlyb through thebottom of the solenoid through an openingiin'tliefbottom of thehousing and In the operation of: device the spring 43'normally keeps the core 41 and its exten sionidrawn up to the uppermost position withthe washer 47 in tight engagement with r the lower edge of the. curled down portion 14 ofthe plate 13, this lower edge thus constituting' a valve seat for the valvecarried by the solenoid. The spring therefore normally maintains the apparatus closed. To dis? charge the s'and current isjsupplied to the solenoid through the conductors 48; "When" energized the solenoid draws down the'zeore 41' which lowers'thehead-eLG and washer 47,,

opening the discharge at the orifice-'14, "as shown in Fig. 3. Sand then passes by gravity throughthe orifice and around the' outer edge of j the washer and; head and downwardlythrough the discharge pipe 2%.

The, flowof sandco'ntinues aslong as the current is maintained the solenoid and stops assoon as the current ceases.

It will be seen that the sanding device-is- I simple in construction, positive in action,

' normally prevents any leakage of sand, and

at the sametime is instantly operableby a "switch loc' ted at any convenient point to effect the track sanding.

7 r The neansof-supportingthe sand recep "20, tacle will of "course vary according to the adaptation madeofit, but it is very readily supportedby straps extending beneath the receptacle outside ofthedischarge conduit 20. igl 1 shows at C such straps secured to d the-trolleyfB' for supporting the sanders 10.

f Fig. 2 shows'at D somewhat differently bent straps for supporting. the sanders on the bridge member A.

charge pipe .24 is. preferably curved to .p'ass 3o downwardly adjacent tothe periphery of the wheel) and terminate a short distance abovethe rail, as shown at in Figsl and 2,] Fig. 2 shows asuitable pipe 50 outside of the tanklO through which the wires 48 7 '35 are-led into, the tank. Eachof the tanks 10 preferably has a suitablecover at its upperend indicated at 16. The removalof this cover allows aquantity of sandto be placed in the; receptacle, which, may entirely inclose the solenoid and itswires, protected by the housing 30 and pipe Thusthetank may carrysuflicient sandto last for a long time. 1 V 1 v 'I have-found that when travelingeranes 45. are equippedwith these sanding: devices the mere running of the bridge member and trolleyover their tracks once'with the sander solenoids energized willv properly sand the track suflicientlyto last fora comparatively longservice. The sander is instantly available for-anyemergency stop, though, for the greatest efficiency of operation, the track periodic applications.
